A lication filed Jury 2,

Taall whom it mag/concern:

Be it known that I, FRANK R. Donate, a citizen ofthe United States, residing at Vandalia, in the countyof Cass and btate of Michigan, have invented certain new and useful Improvements in Stone-Gatherers, of which the following is a specification.

This invention has for its object to pro videlflanimproved road repair implement by which the loose stones and otherobjects are picked up from the road way, carried rear; warclly of the machine over a seriesof separatorbars or rods by which the small stones or other objects are separated from the larger ones, the former being permitted to return by falling to the roadway and the larger stones beingdeposited in a detachable receptacle at the rear of the implement.

Another object is the provision of a machine of this character embodying certain features of adjustment whereby. the scrap ing and conveying elements may be elevated to inoperative position: permitting convenitmt transportation of the wheel mounted frame. lVith these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction, combination of elements and arrangement of parts which will be more fully described in the following specification and setforth with particularity in the claimsappended hereto;

Figure 1 represents a fragmentary side. elevation of the stoneigatherer, the adjacent rear wheel anddrive chain for tlie'rear conveyer supporting shaft being removed,

Fig. 2 represents a top plan view of the gathering machine, 1

i Fig. 3 represents a; longitudinal sectional View therethrough, and,

Fig. 4 represents a-fragmentaryperspective view of the scraper blade detached 1 Fig. 5 represents a fragmentaryperspective View illustratingthe construction of the separator bars, a a

. Fig. 6 is a detail illustrating the manner of mounting the frame; workon the rear axle.

Referring to the drawing-in detail, where? in similar reference numerals designate corresponding parts throughout the several Specification or Letters i ttnt. Patfitd Jan; 18,

views, the t ams 5 indicate a pair er rear supporting. wheels mounted upon a horizontal axle 6 rotatably mounted within the rear terminals of a pairbfforwardly estending: side frame bars? the front poi tions of which 1 converge and are connected 1 to receive a king-bolt 8 pivotally supporting the front terminal of the side members upon a; bolster 9 carrying depending brackets receiving the front supporting wheels 10; A

draftbar 11 i'sattached tothe bolster 9 whereby suitable harness may be applied thereto in order that the stone gather-er may be propelled by draft power or animals. A pair of inclined supporting bars 12is pivotally mounted adjacenttlieirrear terininals upon the axle '6 as iiidioatedat 12 2 and the front terniinals of the rods areconnected by a shoe or scraper blade 13. The edge of the shoe or blade 18 is supported in predetermined position with relation tothe surface of theroadway by casters or ground engaging rollers 1d and forwardly" extending bracket arms 15 aresecured to the terminalsof the blade aiid Carr forwardly diverging fioatingfseraperbla cs 16 which lie outwardly of the terminals of the blade 15 and are designedto deflect obj ects lying upon the surfaceof the roadvvay inwardly of. the. pathbfthe blade.

. The rear terminals of the bars 12 are curved upwardly andprdvi ded with suitable bearingsureceiving a horizontally disposed shaft 1? forminga support. for a pair of spaced sprocket wheels 18 supporting the rear portions of conveyor chains '19 the forward portionsqof which are trained over sprocket wheels 20 secured upon the front and support the. chains 19 in predetermined position with relation to the surface of the roadway and a series offlcdnveyer bars "24 extend transversely between and connect the chains 19 and are adapted to co'dperate with the separator bars to be hereinafter more fully described to convey the stones and other objects to the receivingreceptacle.

A series of rearwardly and upwardly inclined separator bars are secured to the rear portion of the blade 13 and are fastened at their rear terminals to a supporting strip 26 mounted at the upper open end of the receiving receptacle 27 to be movably supported in the rear portion of the machine in order that it may be conveniently removed for convenience in emptying the contents thereof. Alternate bars or rods 25 of the series are-curved as at 28 at their rear terminals .whereas the intermediate rods are doubled upon themselves as indicated at 29 to minimize obstruction to the passage of the stones into the receptacle 27 and thus prevent the material from piling upon the rods25. Y Y

A sprocket wheel 30 is secured to the rear axle 6 and supports a drive chain 31 which thebars 25 by the angular is extended over a sprocket wheel 32 secured to one terminal of the shaft .17 whereby rotary movement of the axle 6 is transmitted to the shaft 17 during travel of the vehicle.

'In operation, the wheel mounted frame is conveyed along the roadway and the loose stones and other material lying thereon are deposited upon the tapered edge of the blade 13 and carried upwardly thereon and along strips 24 of the conveyer chains 19, such stones and other objects being finally deposited in the receptacle 27. The forwardly diverging gathering plates 16 come into contact with the material lying laterally of the terminals of the blade 13 and deflect such material into the path of the blade. The relatively small stones and other objects having a diameter less than the distance between the bars 25 fall between said bars and return to the surface of the roadway and in order that the bladej13 may bev maintained at the desired elevation the medial portion thereof is connected with a chain or other flexible element 33 having connection at its opposite terminalwith a pivoted lever 34 coacting with a suitable looking device 35 whereby the lever may be locked in adjusted position. The-medial portion of the chain 33 is extended over a guide pulley 36 and by proper adjustment of the lever with the shaft .17

clutchtnot shown) the blade 13 may be maintained iniany desired position with relation to the surface 0f the roadway. The sprocket wheel 32 is preferably connected by a preferred type of in order thatthe driving connection between the axle and conveyer' may be broken, when desired, as when the forward terminal of the conveyer is moved to elevated position by proper adjustment of the lever 34.

What I claim is:

1. In a stone gatherer, a road scraping element, a receiving receptacle, and a pluality of resilient separator bars connecting the scraping element with the receptacle, the alternate bars being curved at the terminals connected with the receiving receptacle and the intermediate bars being doubled upon themselves.

2. A stone gatherer comprising a wheel mounted frame, side bars pivotally mounted therein, a road scraping element connected with said bars, road engaging supporting wheels carried by the scraping element, a receiving receptacle arranged reaiwvardly of the scraping element, bars connecting the scraping element with the receptacle, a conveyer frame pivotally supported in the wheel mounted frame, a conveyer arranged thereon, and road engaging supporting wheels carried by the forward portion of the conveyer frame.

3. A stone gatherer including a wheel mounted frame, side bars pivotally mounted therein, a road scraping blade connected with said bars, road engaging supporting wheels carried by the blade, a receiving receptacle arranged rearwardly of the blade, bars connecting the blade with the receptacle, a conveyor frame arranged in the wheel mounted frame and pivotally mounted therein, road engaging supporting wheels carried by the conveyer frame, and means for elevating the blade together with the conveyer frame.

at. A stone gatherer including a wheel mounted f 'ame, side bars pivotal] Y mounted therein, a road scraping element connected with said bars, road engaging supporting wheels carried by the scraping element, a receiving receptacle arranged rearwardly of the scraping element, bars connecting the scraping element with the receptacle, a shaft journaled in the rear extremities of the side bars, a conveyer supporting frame pivotally mounted upon said shaft, a conveyer adapted to travel in said frame, and road engaging supporting wheels carried by the forward portion of the conveyer frame.

5. A stone gatherer comprising a wheel mounted frame, side bars pivotally mounted therein, a road scraping element connected with said bars, a shaft journaled in the rear extremities of the bars, a receptacle arranged rearwardly of the scraping element, bars connecting the scraping element with the receptacle, a conveyer frame pivotally mounted upon the shaft, a conveyer arranged in said frame above the scraping element, road engaging supporting wheels carried by the conveyer frame, and means for elevating the scraping element and moving the conveyer upwardly therewith.

6, A stone gathcrer comprising a wheel mounted frame, side bars pivotally mounted therein, a road scraping element connected with saidbars, road engaging wheels carried by the scraping element, a receptacle, bars connecting the scraping element with the receptacle, a conveyer frame'pivotally mounted between the rear extremities of the side bars, a conveyer arranged in said conveyer frame, and road engaging wheels carried by of the supporting wheels of the scraping element.

In testimony whereof, I afiix my signature hereto.
